“
Note: the star ratings are not absolute, but instead relative to its street price at this time (~$55)
The pl50 represent a good value in budget IEMs, provided you like its particular sound signature and quirks.
The pl50s have a tiny form factor. They are easy to insert and remove, and are more than flat enough to lie down in. Needless to say, they are among the most comfortable...” --JxK

“The review below is for the E10M but the E10 is exactly identical, bar the extra mic. So lets begin.
Packaging:
Mine came in a nice little box with plenty of tips. I tried swapping out the stock ones with each one of them. There’s also an adaptor that allows you to connect the earphones to a laptop or desktop with separate ports for head phone and mic....” --rajeevrn

“This is an update to the review after living with several sets of these beauties for 1.5 years....I now have acquired 7 sets of the e30 with varying amount of time on them ranging from brand new to 500 hours and there is so much variation that I don't know which one to review here, but I will continue in part because I am enjoying them so much and would like to help others who are searching for...” --thelostMIDrange

“So this is my first ever review. Enjoy!
I got my es18's for about $15 in my local store on December last year and I've been enjoying them since. SO let's start!
PACKAGING AND ACCESSORIES:

“I love these earbuds. At the time of writing, these are literally my favorite in ears ever. While Im sure they cant compete with anything over $200, I've never payed more than $45 for earbuds. At the $20 I payed for these, I could cry at how great they sound.
-Bass is slightly boosted, but not overpowering in any way.
-Mids are very in control, seem to be very...” --smitty1ky

“Build Quality: Not much to say than a solid IEM. The outside is "gunmetal" it looks like metal and feels like metal, but then again. I have been fooled before. The clip ...is just a clip, no deficiencies or poor moving around from it. The L shaped 3.5mm jack is also good. No weird wiggling parts, feels and looks solid. As it's an earphone, this section is generally good. The tip of the earphone...” --bowei006
